TriQuint Semiconductor, an RF products manufacturer and foundry services provider, is offering its 77 GHz Gallium Arsenide (GaAs) chipset portfolio for motion detection and adaptive cruise control applications. TriQuint products are currently used by Delphi Automotive in its successful multimode electronically scanning radar (ESR) that enables adaptive cruise control in multiple vehicles. TriQuint 77 GHz chipset devices appeared first in 2010 model year automobiles.

The TriQuint 77 GHz portfolio includes eight products (TS-16949 factory certified) that can be utilized in a variety of design configurations for motion sensing automotive and non-vehicular applications.

In developing its system for Delphi, TriQuint combined time-tested, rugged GaAs designs utilized in defense applications with cost-conscious systems scaled for high-reliability consumer products. TriQuint also developed processes to further enhance performance and reliability including the company’s proprietary CuFlip™ ‘flip-chip’ technology that replaces wire-bonded devices with direct mounts to circuit boards. CuFlip enhances reliability and ruggedness while simplifying overall assembly.

“At Delphi, we were looking for a chipset supplier with a track record of developing high performance products that would help us succeed in the commercial marketplace. TriQuint’s experience with GaAs modules and their ongoing support has helped us to provide our customers game changing driver assist technology,” said Mark Lynn, Chief Engineer, Active Safety, Delphi Automotive.

A multimode ESR with proven solid-state technology is the heart of adaptive cruise control systems like the one developed by Delphi. Its class-leading performance, packaging and durability have helped enable a driver assistance application that not only enhances safety and convenience, but is affordable to more buyers, remarked TriQuint Vice President, Brian P. Balut.

“We’re pleased to support a company like Delphi that has an industry-leading product line-up,” said Balut. “The microwave devices that Delphi has used in its ESR modules are now available for other motion sensing applications that require market-tested, automotive-qualified performance. The products are also cost-competitive for many different motion-based applications and concepts such as security systems.”
